'1 Claim.

This invention relates to a rotary motor, the general object of the invention being to provide a casing and a rotor therein, with pockets in the periphery of the rotor and abutments orvpistons carried by the casing and acting to cause an explosive charge to enter a pocket during the rotation of the rotor with other abutments or pistons acting to compress the charge in the 'pocket, when such pocket reaches such other'abutments with means for firin the explosive mixture and reintroducing it into a pocket in front of another abutment so that the rotor is given an impulse, which the pocket is exhausted when it reaches another point in its revolution.

Another object of the invention is to provide means for moving the abutments or pistons by the rotation of the rotor and with means for preventing leakage between the parts.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which:

Figure 1 is an elevational view with one side part of the casing removed and with parts in section.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is an enlarged fragmentary section on the line 3-3 of Figure 1.

Figure 4 is an enlarged fragmentary section on the line 44 of Figure 1.

Figure 5 is an elevational view with the shaft in section.

Figure 6 is an enlarged fragmentary section on the line 6-6 of Figure 1.

In these drawings the casing is shown at A riphery. The motor is shown and described with the rotor provided with four pockets but it will be understood that the motor can be constructed with any suitable number of the pockets and associated parts.

A pair of substantially opposed inlet ports 6 are formed in one side of the casing 'and these ports are connected with suitable carburetor port 1 is arranged adjacent each of the inlet ports, a suction piston or abutment 8 extending between each pair of the ports 6 and 1. An exhaust pipe 9 enters the casing, through the rim thereof adjacent each of the pistons or abutments 8, these exhaust pipes being connected with suitable manifold means. of substantially oppositely arranged explosive chambers II] are connected with other portions of said side of the casing and each of these explosive chambers is of U-shape with its ends in communication with the interior of the casing by the is located adjacent the inlet end of each chamber I0 and a pressure piston I6 is located adjacent the outlet end of the rotor come opposite the pistons.

Matching grooves are formed in the sides of the casing and in the sides of the rotor for receiving the rings 29 to prevent leakage and radially extending L-shaped packing members 30 the operation of the engine is described with the rotor operating in a counter-clockwise direction as shown by the arrow at in Figure 1. As will be seen during the rotary movement of the rotor as the upper pocket in Figure 1 passes the suction piston B a suction created in the pocket by the piston 8 will draw an explosive mixture through the port 6 and any air in the pocket will escape through the vent port I. Then as this pocket reaches a point where it will be engaged by the compression piston [5 the explosive mixture will be forced by the piston l5 through the port H into the combustion chamber l0 where it will be exploded by a spark from the plug l3 and then the exploded gases will enter the pocket through the port I! and in front of the pressure piston I6. Air or other fluid in the pocket in rear of the piston IE will escape through the vents 32. The action of the expanding gases in the. pocket against the piston pulse and then the pocket reaches the lower exhaust pipe 9 through which the exhaust'gases will pass and then another charge is drawn into the pocket through the lower port 6 While air in rear of the piston 8 will pass through the vent 1. Of course, the explosive mixture drawn into the pocket'will be caused to enter the second combustion chamber where it will be exploded by the spark plug in this chamber and then the gases will enter the pocketin front of the pressure piston l6.

Thus a plurality of impulses is imparted to the rotor to rotate the same. 7

It is thought from the foregoing description that the advantages and novel features of the invention will .be readily apparent.

It is to be understood that changes may be IE will give the rotor its im'- made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claim.

Having described the invention, what is claimed as new is:

In a rotary engine, a casing, a rotor in said casing having concave peripheral pockets therein circumferentially spaced around said rotor and forming together with the inner Wall of the casing fuel containing chambers, means coacting with said pockets in one direction of rotation of said rotor to cause suction in said chambers and including a fuel inlet port in one side of the casing through which fuel is drawn into said chambers under the action of suction created therein, abutments slidably mounted in said casing in ad- Vance of said first means operative to enter said pockets as the latter are rotated past the same to form partitions therein forcing the fuel in said chambers rearwardly and thereby compressing the same, means providing for passage of the compressed fuel from said chambers from the rear of the partitions back into the chambers in front of the partition, means to ignite such'fuel within said by-passing means, and means for variably tensioning said abutments to cause the same to ride on said rotor and enter said'pockets with uniform pressure against the rotor and bottoms of the pockets comprising caps at the outer ends of the abutments, cam grooves in the opposite sides of the rotor, arms slidably mounted, on opposite sides of the casing and provided with angular ends projecting into said' grooves, and springs connecting said arms to said caps;
